I don’t use these tubes, but what’s the point of responding to a question with essentially, ‘those are great/amazing tubes, I have dozens of pairs that I’ll never use/sell/share, and good luck finding any because I’ve hoarded them all’…?? If the tubes are that good why not get them out there for others to enjoy?
6SN7GT VT231 TUBES
I love the old VT231 tubes!
The best sounding 6SN7GT ever...Sylvania, Raytheon, RCA, Ken Rad Etc. They may still be found, if you have $$$!! Where can I find true NOS VT231s? Any favorites that I missed?
(TS never made a VT231 - but their old black glass tubes with oval micas sound great!)
